NGC 287 is a lenticular galaxy in the constellation Pisces. It was discovered on November 22, 1827 by John Herschel. [3]
NGC 188 is an open cluster in the constellation Cepheus. It was discovered by John Herschel in 1825. Unlike most open clusters that drift apart after a few million years because of the gravitational interaction of our Milky Way galaxy, NGC 188 lies far above the plane of the galaxy and is one of the most ancient of open clusters known, at approximately 6.8 billion years old.
NGC 1265 is a Fanaroff and Riley class 1 radio galaxy located in the constellation Perseus, a member of the Perseus Cluster.
NGC 51 is a lenticular galaxy in the constellation Andromeda. It has a diameter of 90,000 light-years. The galaxy was discovered on September 7, 1885 by Lewis Swift, who described it as "Pretty faint, pretty small, round, brighter middle."
NGC 262 is a spiral galaxy in the cluster LGG 14. It is a Seyfert 2 spiral galaxy located 287 million light years away in the constellation Andromeda. It was discovered on September 17, 1885 by Lewis A. Swift.
NGC 2748 is a spiral galaxy in the northern circumpolar constellation of Camelopardalis, located at a distance of 61.3 megalight-years from the Milky Way. It was discovered September 2, 1828 by John Herschel. The morphological classification of SAbc indicates this is an unbarred spiral with moderate to loosely-wound spiral arms. It is a disk-like peculiar galaxy with a stellar shell that is rotating about the main galactic axis. This shell was most likely formed through the capture and disruption of a dwarf companion. The galactic nucleus likely contains a supermassive black hole with a mass of 4.4+3.5
−3.6×107 M☉, or 44 million times the mass of the Sun.
NGC 128 is a lenticular galaxy in the constellation Pisces. It is approximately 190 million light-years from the Sun and has a diameter of about 165,000 light-years.
NGC 171 is a barred spiral galaxy with an apparent magnitude of 12, located around 3 million light-years away in the constellation Cetus. The galaxy has 2 main medium-wound arms, with a few minor arms, and a fairly bright nucleus and bulge. It was discovered on 20 October 1784 by William Herschel. It is also known as NGC 175.
NGC 184 is a spiral galaxy located in the constellation Andromeda. It was discovered on October 6, 1883 by Édouard Stephan.
NGC 259 is a spiral galaxy located in the constellation Cetus. It was discovered by William Herschel in 1786.
NGC 269 is an open cluster in the Small Magellanic Cloud. It is located in the constellation Tucana. It was discovered on November 5, 1836 by John Herschel.
NGC 304 is a lenticular galaxy in the constellation Andromeda. It was discovered on October 23, 1878, by Édouard Stephan.
NGC 315 is an elliptical galaxy in the constellation Pisces. It was discovered on September 11, 1784 by William Herschel.
NGC 318 is a lenticular galaxy in the constellation Pisces. It was discovered on November 29, 1850 by Bindon Stoney.
NGC 333 is a lenticular galaxy located approximately 755 million light years away in the constellation Cetus. It was discovered in 1877 by Wilhelm Tempel. It is recorded as NGC 333 in the New General Catalogue. It has a companion galaxy, named PGC 3073571, which is presumed to be a physical pair with NGC 333.
NGC 7079 is a barred lenticular galaxy located about 110.58 million light-years away in the constellation of Grus. NGC 7079 is also classified as a LINER galaxy. It is tilted about 51° to the Earth's line of sight. NGC 7079 was discovered by astronomer John Herschel on September 6, 1834.
NGC 4098 is an interacting pair of spiral galaxies located 330 million light-years away in the constellation Coma Berenices. NGC 4098 was discovered by astronomer William Herschel on April 26, 1785. It was then rediscovered by Hershel on December 27, 1786 was listed as NGC 4099. NGC 4098 is a member of the NGC 4065 Group.
NGC 605 is a lenticular galaxy in the constellation Andromeda, which is about 234 million light-years from the Milky Way. It was discovered on October 21, 1881 by the French astronomer Édouard Jean-Marie Stephan.
NGC 622 is a barred spiral galaxy located in the constellation Cetus about 234 million light-years from the Milky Way. It was discovered by British astronomer William Herschel in 1785.
NGC 803 is a spiral galaxy located in the constellation Aries about 70 million light-years from the Milky Way. It was discovered by the German–British astronomer William Herschel in 1784.
